Lacerda's Cory, scientifically known as Scleromystax lacerdai, often referred to in the aquarium trade by its identification number C015, is an attractive and somewhat rare species of Corydoras. Originating from the coastal rivers in southern Brazil, this species is notable for its striking appearance and is sought after by aquarium enthusiasts who appreciate unique and less common catfish.

Lacerda's Cory exhibits a robust and elongated body, characteristic of the Scleromystax genus, which tends to be slightly larger and more elongated than the typical Corydoras species. The fish displays an intricate pattern of black markings over a lighter background, which includes a distinctive, bold stripe along the lateral line and splotches or bands across the body and head. The males are particularly colorful, especially during breeding periods, which makes them even more appealing.

In the home aquarium, Lacerda's Cory requires conditions that closely mirror its natural habitat. The tank setup should include a soft substrate such as sand to prevent damage to their delicate barbels. They appreciate a well-planted aquarium with plenty of hiding spots provided by driftwood, rocks, and vegetation. This setup not only replicates their natural environment but also helps to keep the fish comfortable and stress-free.

Water quality is crucial for maintaining the health of Lacerda's Cory. The water should be kept clean and well-oxygenated, with a gentle flow that mimics their natural riverine habitat. Regular water changes are essential to maintain the water quality, and the use of a good filtration system helps to keep the tank environment stable.

The diet of Lacerda's Cory should be varied and balanced to ensure they receive all necessary nutrients. They are primarily bottom feeders, consuming a diet that includes high-quality sinking pellets, flakes adjusted for bottom feeders, and a variety of live or frozen foods such as bloodworms, daphnia, and brine shrimp. Supplementing with occasional vegetable matter can also be beneficial.

Breeding Lacerda's Cory can be challenging but rewarding. They are egg layers, with females laying eggs on the tank glass or vegetation after a delicate mating dance performed by the males. Creating the right breeding conditions, including slightly cooler water changes and a diet rich in high-protein foods, can encourage spawning.

Conservation is important for Scleromystax lacerdai, as habitat loss and environmental changes pose threats to their natural populations. Sustainable practices in the aquarium trade are crucial to ensure that the demand for these beautiful fish does not adversely affect their wild populations.

Overall, Lacerda's Cory is a delightful addition to any aquarium, especially for those looking to keep a more unusual and visually striking species. Their care and maintenance require a bit of experience, making them more suitable for aquarists who have some knowledge of keeping similar species.
